Olafur Eliasson (Copenaghen, Denmark, 1967) places viewers at the center of his artistic investigation. Utopian and subtly revolutionary, the work of Eliasson, who is of Icelandic descent and grew up in Denmark, unites the memory of an encounter with nature and the broad realm of science and political thought. Devices constructed to re-propose the power of natural elements or to produce certain perceptual phenomena, his pieces become works of art when they encounter the viewer, and come alive by reiterating the unique and ephemeral character of that moment. Avoiding romanticism, the apparatus that enables the work to function is part of the work itself and is often based on simple technology or processes that pertain to everyday life. As a shared experience, but tied ultimately to the individuality of each observer, the act of seeing is the object of continuous exploration on the part of the artist. Many of his works are conceived to develop in viewers the awareness of their specific visual capacities that cannot be replicated by others. A result of his encounter with the architecture of the Castello di Rivoli, Your circumspection disclosed, 1999, is, in the artist’s words, “an extension of the eye, or rather a machine for seeing.” Structured to transform the visual process into a physically negotiable experience, the installation is organized into two spaces separated by a wall pierced by a single small hole.
